PULLEY-SEIELD DEVICE.

Application filed February W, 1922.

T all to ham it may concern Be it known that 1, Fans ()Hnnnow, a citizen of the United States of America, and resident of Rockwell, in the county of CQII'O e" Gordo and State of Iowa, have invented certain new and useful Improvements in Pulley-Shield Devices, of which the following is a specification.

This invention relates to a shield or mud M) guard for tractors, and particularly to a tractor of the Fordson type whereby provision may be made for using the tractor with the belt driving pulley mounted thereon without liability of the said pulley adversely affecting the use or operation of the tractor.

It is a well known fact that when a tractor of the character indicated having a pulley thereon is in transit or is moving, earth and stones displaced from the traction wheel lodge on the pulley and are then thrown therefrom by centrifugal force, to such an extent as to render the use of the tractor in this condition unsafe or at least inconvenient, and it is the purpose of the inventor, therefore, to provide novel means which will shield or guard the pulley to prevent the earth and loose stones fromv falling on the said pulley; and further to prevent the dis sipation or throwing of such earth or stones in directions which might impair the driver.

Heretofore in the use of the tractor of the character indicated, it has been customary to partly dismantle the tractor to remove the pulley when the belt is to be dispensed with and the machine is to be used for field work. Such partial dismantling occupies a great deal of time and its re'-asse-mbling furthermore occupies a great deal of time, all of which is saved by the use of this invention.

One skilled in the art will understand that in order topartially dismantle the tractor to convert it for the uses stated, the removal of the plate of the transmission housing must be accomplished and a great deal of other Work performed, whereas the application of the shield of this invention, which can be applied in a very short time, will obviate the expenditure of time necessary to make the changes heretofore required.

It is a further object of this invention to produce a shield of the character indicated Which can be readily and quickly applied to or removed from the tractor, the same Serial No. 538,803.

being comparatively inexpensive and eiiicient and satisfactory in use.

d i ith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application 85 wherein like characters denote correspondlng parts in the several views, and in which- Figure 1 illustrates a view in elevation of a fragment of a tractor, showing a device embodying the invention applied thereto;

Figure 2 illustrates a sectional view of the shield, showing the anchoring means in elevation; and

Figure 3 illustrates a perspective view of the said shield.

In these drawings 5 denotes a casing having a pulley 6 mounted on a drive shaft 7. The casing has a plate 8 bolted to it and it is in conjunction with this plate that the bracket 9 coacts. The inner end of the bracket extends downwardly and the outer face thereof is concaved as shown at 10 or of such configuration as to conform to the contour of the casing to which it is applied. The extension 10 has an aperture 11 for the reception of one of the stud bolts 12 by which the pulley housing is secured to the casing, the said pulley housing and plate 8, in the present construction, being integral 90 and having a raised portion forming a shoulder 13 against which the end 14: of the extension of the bracket lies, the said end of the extension being shaped to the contour of the said shoulder. As shown in Fig; 3, the end of the angularly disposed portion of the bracket is widened compared with the width of the angularly disposed portion, and this forms a foot-like construction which increases the bearing surface of the said extension on the raised portion of the pulley housing, so as to prevent turning of the bracket of the pulley shield when the parts are properly assembled.

The body 15 of the pulley shield is curved 105 and is approximately concentric with the periphery of the pulley, but the bracket or the extension thereof is of such length as to maintain the pulley shield in spaced relation to the pulley, in order that it will not 110 interfere With the rotation of the pulley While the tractor is being run.

-A device made in accordance with this invention can, heretofore stated, he quickly applied to or removed from a tractor, so that when the tractor is to he used in the different capacities, it can be converted speedily.

I claim:

1. In a shield for tractor pulleys, a treetor having gear cesingr a plate applied to the gear casing, said plate having at raised portion forming ashoulder, a bracket hit? ing an apertured extension shaped to the contour of the gear casing and a foot, the edge of which engages the edge oi' the raised portion or the pldte the said bracket projecting: over the pulley of the tractor, and 21 shield by the said hrecket. LA. a shield for e pulley oil a tractor, a bracket having extension at an angle thereto, a p having shoulder, the said extension hzwi an aperture to receive a stud of the tractor to maintain an engagement 01 the ciid of the extension of the bracket with the said shoulder and a. shield carried by the said t.
